HEAD-MOTION.

Losetas.

To all /w/Twm t may concern Be it known that I, FRANK FRANZ, residing at liVallace, in the county ot Shoshone and State of ldaho, have invented certain new and useitul Improvements in Head-Motions, of which the following is a specification.

My invention is an improved mechanical device tor imparting longitudinal reciprocation to ore concentrating' tables, and the invention particularly resides in those novel features ot construction, combination and arrangement of parts, all of which will be first 'fully described, and then be specifically pointed out in the appended claims, reference being' had to the accompanying drawings, in which Figure 1 is a vertical longitudinal section on the line 1-1 ot Fig. 2. Fig. 2 is a top plan view and part horizontal section ot my invention. 3 is a detail cross section on the line 3-3 of Fig. 2.

ln the drawings in which like numerals and letters ot reference indicate like parts in all the ig'ures, 1 designates the base or support, which is provided with suitable bearings 2 2, tor the driving shaft 29, and which is also provided with a bearing 3 tor the pusher pin or rod 5 which is carried on the bracket 8 to which the table 13 is bolted. The base 1 also includes the standard l in which the adjusting screw 12, that engages the spring` block 10, is mounted.

9 designates a boss projecting in alinement with the rod 5, and over which, the end ot the spring 10 is fitted.

7 designates an oiling aperture for the bearing 6, which is lined with suitable bearing metal as indicated.

14e is a standard which supports a screw 15 on which a hand wheel 16, is mounted, the hand wheel 16 having a grooved collar to receive the adjustiiremembers 17, which carries the socket block 13. ylhe block 13 is provided with a socket in which the cylindrical head 2() ot the link 21, is mounted.. The block 13 is provided with an oiling duct 38 'for the bearing head 20, as indicated. 19 is another socket block which is fitted over the end ot the rod 5, and has a socket to receive the cylindrical head 23 of the main toggle member 25. The block 19 is also provided with an oil duct 37, as indicated. llhe main toggle member 25 has a table por- Specifcaton of Letters Patent.

tion 2&1-, on which a wear plate 32 of liber or the like is mounted, and the table 211 has a lubricant pocket 26, in which suitable lubricant is held, to tlow through an oil duct 27 tothe socket bearing that receives the cylindrical bearing' head 22 ot the supplemental toggle link 21. The oil pocket is filled with waste and oil and closed twothirds from the bottom.

28 designates a plug for closing the oil pocket 2G.

The shaft 29 carries a cani 30 that operates in a ring 31, the cam 30 having1 a shouldered portion 3/1- and being provided with a cap plate 35 to retain the ring 31 in place. The ring 31 is provided with an oil pocket 33 to collect and retain the necessary lubricant. The plate 35 is held on by bolts 3G as best indicated in Fig. 3 of the drawings.

39 is the fly wheel, also the belt pulley.

Ll() is the loose pulley so the machine can be stopped when desired.

ln the practical operation ot' the invention, motion is imparted to the shaft 29, whichturns the cam 30 in one direction or the other7 thereby causing an opposite rotary movement to take place in the ring 31. is the cam 30 turns, the plate 32 will be moved downwardly, and thus cause a separation to take place between the blocks 13 and 19, thereby moving` the pin or rod 5 trom left to right in Fig. 1, against the tension ot the spring 11. As the shaft 29 turns Jfarther to raise the cam 30, the spring- 11 will move the block 19 toward the block 18, and consequently hold the plate 32 in continuous contact with the ring` 31.

In order to adjust the stroke ot the rod 5, and consequently the stroke of the table 13, it is necessary to but raise or lower the bearing` 13 by turning the hand wheel 16.

From the foregoing description taken in connection with the accompanying drawings it is thought the complete construction, operation, and advantages oit the application will be apparent to those skilled in the art to which it appertains.

1. ln a head motion tor ore concentrators, a supporting trame, bracket member having a shaft or pin, a bearing` on said trame in which said shaft or pin is mounted` yieldable means coperative with said pin and Vbracket and continuously tending to move said bracket in one direction, an abutment carried by said frame and spaced from said bearing, a shaft rotatably mounted between said abutments and in a plane above the same, and extending in a direction transverse to the anis of said pin, a bearing member adjustably mounted on said abutment and including a socket portion, a bearing member carried by said pin, and also including a socket portion, a cam mounted on said transverse shaft, a main toggle lever including a flat upper bearing surface adapted to be held up in contact with said cam, and also including a downwardly projecting portion terminating in a bearing end to enter the socket of said pin carried bearing member, said main toggle member including a bearing socket beneath said flat surface, and a downwardly projecting toggle link having a bearing end held in said last named socket, and having a second bearing head held in the bearing socket of said adjustable bearing member, all being arranged whereby said yieldable means Will also serve to hold said main toggle member in contact with said cam at all times, substantially as shown and for the purposes described.

2. ln a head motion, a supporting frame, a bearing mounted thereon, a bracket member having a rod portion slidable in said bearing, a bearing block mounted on the end of said rod portion, said frame including an abutment, a bearing block engaging said abutment, a main toggle member having a bearing end engaging said bracket rod bearing member, a Second toggle member having bearing members for engaging said abutment bearing member and said first toggle member, a vvear plate mounted on said first toggle member, a rotatable shaft, a cam on said rotatable shaft for effecting the movement of said toggle member, and resilient means continuously tending to move said bracket member in a direction to continuously tend to move said toggle members toward said shaft.

3.
